In constructing my platform, Iprovide ,a basal support or seat for each spring. This basal siipport E (see Fig.4) has a depression or channel E present at each 'end. One 'or more openings E in this depression formed by elevating the bottom of the depression at" E serve to receive the lower end of the spring. The latter is passed through these openings E and held .in position in the channel E This is the preferred 'mode of securing it to this seat E. Each end of this seat E is bent around in the form of a roll E*. To connect these basal supports or seats E is the fiinction of the'rod frame D. This frame has the inclined sides D and the flat sides at D D and these straight sides are respectively received into the adjacent rolls E, E oftwo seats Ef see Fig. 3. The ends D and D of these rod frames D are securedto the adjacent ends of similar rod frames, substantially. as shown. The

HENRY HIGGIN, or NEWPORT, KENTUCKY, Assienon TO THE HIGAGIN MANUFACTURING rod frame has a straight end D The other end consists of the ends-D D'- of the rod, and each of these ends is ,curved over, respectively forming similar terconnected. It is necessary to connect this bottom construction thus far described to the bottom frame A. To effect this connection, I provide the device H'for connecting" the straight part -D of "a hook D to the frame. -This part D is embraced in the hollow cylindrical or curved end H of the piece H. The piece H is preferably provided with the extended portion H so as to drop the curved part H below the topof the frame, and allow the bottom part of the platform to be lower down. A part H of the piece H is preferably present, being the preferred means for securing the piece to the frame. Bolts or screws or nails are in such case passed through the holes E into the frame A. To secure the basal supports or seats to the frame, I provide a device, see Fig. 10, consisting of a link F,

suitably secured in anoscillatory manner to the seat- I E and to the frame A. A. preferred kind of such connection is as follows: The plate G is bolted at G to. the top of the frame A and in its hollow cylindrical 'or curved end G is contained one side F of the link F, free to turn therein, The opposite side F? of this link is contained in the adjacent curved .end E of the seat E and-is free to turn therein, see Fig. 3.

. It often desirable to leave some space between the spring platform and the rear part of the frame A. Y

This is especially the case on large chairs where the back is upholstered'and extends forward for a distance in front of the frame ofthe back of the chair.

In such event, I provide a device-for connecting the rear part of the platform to the rear part of the frame Fig. 11, namely: the rod has a straight portion I and by a suitable device. J'The preferred form oft device therod frame of the straight portion K is bent into 'cessively the upper rod of the spring 0 and the rod of the upperfrain'e B. When the clip is thus located around these 'parts just mentioned, thehooks M are bent up- A, or its equivalent. This device consists, see Fig. 11, of a connecting rod, preferably made as shown in sides 1 ,1 whichconverge so that the ends I", I meet as shown and are each curved at I These curved ends I I constitute a single hook, which grasps a straight portion D of an adjacent rod\ frame D. The straight part I ofthe rod is pivotally connected to the frame preferably by a piece J, bolted, nailed or screwed to the top of the frame at J and having at its edge a hollow .cylindrical'or curved portion J which loosely embraces the straight part I of the rod- 1, and leaves the latter free 'to turm therein. i The construction of the upper portion of the spring platform is substantially as fo11ows:Iprovide a rod frame Kwhich is substantially like red frameD namely: having a straight end K. The opposite end of the frame is provided with a hook. This hook prefer ably consists in making each free end K, K ofthe rod frame of a hooked form K K These hooks turn the same way and together form a'= single hook. Between the end K and the hook K on each side is a straight portion K and for the purpose 'of enabling eachside to be readily attached to its adjacent spring,

the form of an eye, so that there. is a straight portion K provided at each end with an eye portion K. The

u'pper rod of the adjacent spring is passed through these eyes K K and is thus held firmly in position.

This clamping device just described is efficient. The

connection between these rod frames K and the spring beyond the ends K K, K of the rod frame is preferably 'made by means of a device such as L. This connection consists of two rods L L each of the rods at one end being provided with'an eye L and such eye embrac es an upper wire or rod of .an adjacent spring. The other end of ohe' set of these connections L is provided witha hook L These hooks engage the straight part .K of therod frame K. Inasmuch as the pieces K of rod frame converge toward the straight part K the hooks L will not slip laterally.

The rods L L at the other end of the'rod frame are preferably made integral at L and a hook there is omitted, a straight portion L being present where the hooks wouldha've' been. The hooks K K of the rod frame K engage this straight portion L For a full, understanding 'of'these constructions, see Figs.

2and 7. v L 3 Theu'pp'er end f theispring C may be connected to the upper frame B -of the springv platform in Various ways. The connectionmay be made by weldihgflor :for'uniting the iupperend of'the spring 0 to the upper frame '13 of the spring platform is as follows :I provide a hooked clipM, shown in Fig. 5, consisting in detail of the straight portion'M united to shoulders M These shoulders M are continued in the pieces M,

hooks Befo're this device is applied, there is a space, see Fig. 5, between the straight portion M and thelfree ends of-the hooks M sufiicient to admit sucward"-.and down at the sides of the straight portion M The clip ,thus closed embraces the adjacent part of the spring Qand the adjacent portion of the rod frame B as shown in Fig. 6, v i

Many of the parts of myinventioii have an advantage resulting from their individual construction, and many of them have an advantage arising from their connection with other parts of the mechanism.

A great many slight changes inight be made in the general form and arrangement of the parts described without departing from my invention, and hence I do not confine myself to the precise details set forth, but consider myself at liberty to make such slight changes and alterations as fairly fall within the spirit and. scope of my iny ention.

The seat E is very rapidly manufactured and affords a thorough support'for the spring. At the same time connection-is quickly made withthe adjacent rods. The part E thus constitutes not only a seat, but a link very convenient, very cheap of construction, easily applied and effective in use. The rod frame D of Fig. 8 is very simple, easily constructed and very strong. The same is true of the rod frame K, and its eyes K afford a very valuable addition to this simple device, thataltho gh valuable in use are cheap of manufacture. The parts L L with their terminals as described are easy of manufacture and strong in use. The piece H provided with its hollow cylindrical part or sleeve H? provides an attachment which is strong, not readily distiirbedand holds the rod frame securely to the lower frame. 1

The device shown in Fig. 10 is a valuable link and is very convenient, connecting the seat.E to the lower frame A. The rod frame I of Fig. 11 pivotally connected to the piece J and the hooks 1 I is simple, strong and allows the platform an extended oscillation up and down. The entire platform when united substantially as shown is of great elasticity and remarkable strength. A man can'stand upon one corner of this spring platform and jump up and down without deranging it, and after he steps off, it will resume its voriginal position. In many cases, particularly in the, seats of road and similar vehicles, the lower frame A,

that in chairs is usually of wood, will preferably be of metal, and of a rod formf In suchcvent, it will he usually desirable to omit the links and have the metal rod frame engage directly one of the curved ends E of the spring seat.
